Skystack

Features
Read full description

Skystack is a one-tap tower stacker that's easy to start and hard to put down. A block slides back and forth. Tap to drop it. Line it up perfectly and your tower grows, the music climbs the scale, and your combo soars. Miss, and the block gets sliced thinner. The higher you go, the faster it gets — until it all comes tumbling down and the camera pulls back on the tower you built. A round lasts about 30 seconds. You'll play a lot of rounds. • One-handed, one-tap controls — pick up and play • Perfect-drop combos with rising musical feedback, particles and haptics • Six unlockable color themes, plus season-exclusive looks • A new battle pass every month — 20 tiers of rewards • Lifetime mission tracks, daily and weekly challenges • Daily streaks that keep the coins coming • Apple Game Center leaderboards — weekly global ranks and friends Fair by design. Purchases are cosmetic or convenience only — no pay-to-win, no loot boxes. The pass sells looks, not power. How high can you rise?
